Having trouble with the attached problem on test score, when i get the (x1bar-x2bar)/SE the answer is not coming out right, i was getting (39.29-30.29)/1.3 , I am just attempting to get the Test Statistic.
OUTLET Deluxe $ Standard $
1 40 27
2 39 28
3 43 35
4 38 31
5 40 30
6 39 32
7 36 29
The manufacturer's suggested retail priced for the two models shows a $10 price differential. Use a .05 level of significance and test that the mean difference between the prices of the two models is $10
What is the value of the test statistic?
